Abstract

Cultivating lettuce (Lactuca sativa L.) using plant growth-promoting rhizobacteria (PGPR) in Sorong Regency is uncommon, limiting production despite the high market potential. This study aims to evaluate the effect of PGPR and identify the optimal concentration to improve lettuce growth and yield. The research was conducted in Malawili Village, Sorong Regency, Indonesia, using a randomized block design (RBD) with four treatments: P0 (7.5 mL/L), P1 (10.5 mL/L), P2 (13.5 mL/L), and P3 (16.5 mL/L). Results revealed that PGPR significantly enhanced growth parameters, including plant height, leaf number, fresh biomass weight, biomass weight per plot, fresh weight for consumption, and root length. Among all treatments, 13.5 mL/L (P2) demonstrated the best outcomes, with plant height reaching 14.6 cm, fresh biomass weight of 633.3 g, and root length of 9.6 cm. PGPR application at appropriate concentrations effectively stimulates growth, increases nutrient uptake, and improves yield. These findings underline PGPR's potential to enhance lettuce production sustainably.

Abstract

This thinks about points to create an appraisal of thinking skills of interpretation, analysis, and inference through analytical essay assessment instruments, worksheets, and problem-solving. Preliminary investigation of the advancement of basic considering aptitudes assessment instruments for prospective Physics teachers in the last 3 (three) years in the Basic Physics course, the test instruments in the Basic Physics course have not been fully oriented to indicators of interpretation, analysis, and inference thinking skills. The process of changing Physics learning, both at the tertiary level and at the secondary school level, is directed at training students to use their thinking potential. One of the Physics learning skills mentioned in Permendikbud Number 64 of 2013 is the development of thinking skills of interpretation, analysis, and inference. This shows that the process and evaluation of learning physics, especially basic physics, should be directed at developing thinking skills in interpretation, analysis, and inference. This inquiry is spurred by the requirement for an appraisal instrument that measures critical thinking skills, especially interpretation, analysis, and inference thinking skills. This study aims to develop an assessment of thinking skills of interpretation, analysis, and inference through analytical essay assessment instruments, worksheets, and problem-solving. This study refers to the 4D Thiagarajan model and produces an assessment that measures the ability to think of interpretation, analysis, and inference. The test instrument was created within the shape of essay analysis, and problem-solving on indicators of thinking skills of interpretation, analysis, and inference. The test instrument was further validated by two experts, and it can be concluded that the created test is exceptionally attainable to utilize.

Abstract

in DC motor experiments to understand the concepts of power, momentum, and force. The urgency of this research lies in the need to bridge the gap between physics theory and practical applications, which can help students better understand abstract physics concepts. This research employs a STEM-based approach that integrates technology and hands-on experiments, where the Arduino Uno acts as the main controller in the experiment. The method used involves a DC motor experiment controlled by Arduino, measuring variables such as voltage, current, and motor speed to analyze the relationship between power, momentum, and system efficiency. The data obtained from this experiment is used to calculate power, momentum, and efficiency, providing insights into the conversion of electrical energy to mechanical energy. The results show that the STEM-based experimental approach with Arduino is effective in enhancing students' understanding of fundamental physics principles and modern technology applications. The use of Arduino enables more accurate measurements and precise control over experimental variables. This study also finds that the experiment can improve students' technical skills in programming and microcontrollers, supporting STEM education.

Abstract

The research analyzes the educational experiences of rural junior high school Indonesian language teachers by examining their teaching competence improvement barriers. A qualitative method enabled researchers to obtain data from classroom observations together with in-depth interviews and focus group discussions involving twelve teachers who teach at different rural educational facilities. Research demonstrates that rural teachers experience important barriers because they face restricted access to basic resources together with restricted access to professional development and technological support. Despite these obstacles, teachers employ various strategies for self-improvement, such as peer collaboration, online learning, and community support. Rural teachers receive essential help from neighborhood residents who provide facilities along with encouragement to bridge their educational deficiencies. This research demonstrates both the significance of nonformal professional support systems used by teachers as well as their ability to cope with their individual teaching situations effectively. Rural schools need both enhanced organizational backing and stronger community involvement to build teacher qualification levels which produces better academic outcomes in their areas. The study contributes to research overlooking rural education while providing concrete suggestions for authorities and education leaders to enhance teacher development in underserved rural regions.

Abstract

Banana peel is a carbohydrate-rich by-product with potential as a fermentation substrate for enzyme production. This study aimed to evaluate the amylase production and storage stability of enzymes obtained through solid-state fermentation (SSF) of banana peel flour using Bacillus subtilis and Bacillus licheniformis. Fermentation was conducted for 24 and 48 hours, followed by crude enzyme extraction and storage for 24 hours at room temperature. Proximate analysis revealed banana peel flour contained 78.64% carbohydrates and 46.24% starch, supporting its suitability as a fermentation medium. The highest amylase activities were 50.36 IU/mL/min (B. subtilis) and 56.33 IU/mL/min (B. licheniformis) after 24 hours, with comparable values at 48 hours. However, enzyme activity declined by over 78% after 24 hours of storage, indicating low stability at room temperature. These findings confirm that banana peel flour is an effective, low-cost substrate for amylase production via SSF. Nevertheless, stabilization strategies post-fermentation are crucial to preserve enzyme activity during storage. This study highlights the dual benefit of converting agricultural waste into valuable enzymes and supports further research on improving enzyme shelf-life for industrial applications.
